The building, which is named Amagerforbraending,
was the unanimous winner of an international competition to replace
the 40-year-old plant that currently exists on the site. It'll
occupy 95,000 square metres, 31,000 square metres of which will
become ski slope, totalling 1,500 metres of green, blue and
black-diamond ski runs.

The centre of the building houses a massive smokestack, which
lifts run alongside to ferry skiers up to the top. The inhabitants
of those lifts can see inside the plant while they ascend. The
smokestack belches a 30-metre-wide smoke ring into the sky every
time a tonne of CO2 is released, so that locals are able to get "a
gentle reminder of the impact of consumption".

Even better, at night those smoke rings will be illuminated by
heat-tracking lasers, which will project a pie-chart onto the smoke
that displays a quota of fossil-fuel CO2.

The proposal reads: "Most of the recently built power plants are
merely functional boxes wrapped in an expensive gift paper. We want
to do more than just create a beautiful skin around the factory. We
want to add functionality!"

It continues: "Instead of considering Amagerforbraending as an
isolated object, we mobilise the architecture and intensify the
relationship between the building and the city, expanding the
existing activities in the area by turning the roof of the new
Amegergorbraending into a ski slope for the citizens of
Copenhagen."

There's plenty of lovely shots of the building in the full proposal, and
there's also small gallery of them above. If you want, you can even
